Abstract

Cloud computing has been established as a technology for providing needs-orientated and use-dependent IT resources, which now are being used more frequently for business information systems. Particularly in terms of integration of decentralized information systems, cloud systems are providing a stable solution approach. Still, data security is one of the biggest challenges when using cloud systems and a main reason why many companies avoid using cloud services. The question we are facing is how cloud systems for integration of decentralized information systems have to be designed, in terms of technology and organization, so that privacy laws of the cloud user can be guaranteed. This contribution summarizes the results of a system comparison of decentralized cloud systems in social networks, a requirements analysis based on a literature analysis, and a model for organizational levels of cloud systems, derived from the requirements analysis.

Conclusion

This contribution introduced research artifacts in order to answer our research issue: How must a cloud-based ecosystem for the integration of decentralized information systems be built technologically and in terms of organization, in order to guarantee cloud users their privacy laws? In order to structure the problem, a system comparison from the field of social networks was carried out, and basic forms of the organization of cloud systems were analyzed. It became clear that peer-to-peer approaches as technological realization are favored since they do not require trust toward the centralized authority. Additionally, the users need to run their own systems. From the then conducted literature analysis, 27 requirements for the implementation of decentralized systems with the focus on data security were raised. It was shown that trust is a key element when it comes to data security aims and that users are becoming more involved in the process of creating services. Finally, various organizational levels for a division of roles in cloudbased ecosystems were introduced. The presented model can be used for the application of already existing concepts and as a support for the conceptualization of new approaches.
